MANTLE FUR INVEBTED INCANDESCENT GAS-LAll/IPS AND METHOD OF TYING THE ME 1,1ll4h515.

Patented July 21, 1914.

Original application filed February 17, 1911, Serial. No. 609,194. Divided and this application filed February 24, 1913. Serial No. 750,053.

To all whom it may concern Be it known that 1, Emma L. KNoEpLnR, a citizen of the United States, and resident of Gloucester City, county of Camden, State of New Jersey, have invented a new and useful improvement in Mantles for Inverted Incandescent Gas-Lamps and Methods of Tying the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawlngs, 1n which- Figure 1 is a side elevation of a mantle secured to the supporting ring, showing the manner of tying the mantle on the ring; Fig. 2 is a perspective view of the doubled loop employed in the string; and F1g. 3 IS a s1de elevation of the finished mantle after it has been turned.

My invention relates to mantles for inverted incandescent gas lamps and is designed to provide an improved invert-ed mantle having the securing cord entirely hidden within the fold of the mantle while, at the same time, improper drawing of the mantle around the ring is avoided.

To that end the invention consists in such a completely hidden cord having a double loop with a knot also located within the fold.

It further consists in a tying cord having a single knot hidden in the fold.

It further consists in the method of applying and tying the cord.

The precise nature of my invention Wlll be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction of the mantle and support ing ring without departing from the spirit and scope of my invention as defined in the appended claims.

Referring to the accompanying drawings, the numeral 2 designates the mantle, 3 the supporting ring, and l the cord for securing the mantle to the ring.

The mantle blank is first placed in position around the supporting ring, the ring and mantle being supported in any desired manner. I then place the tying cord around the ring and mantle with two loops, as

shown in Figs. 1 and 2. These loops are drawn tight and as they are drawn by the knot at one side, one loop will tend to draw the mantle in one direction, whilethe other loop will tend to draw the mantle in the other direction, and both of said loops will clamp-the mantle so that the drawing of the mantle by one loo-p will be prevented by the other loop. It is therefore evident that by using two loops, the sidewise draw on the mantle is prevented so that there is no tendency to pull the mantle around the ring toward the knot. If a single loop is used, as the knot is drawn tight the mantle fabric is drawn around toward the knot by the movement of the loop and the mantle fabric must then be pulled back and equalizedv by the operator. The double loop formation does away with this difiiculty and prevents drawing the mantle around the r ng. After the knot has been tied, the mantle is turned back and finished in the usual manner.

The advantages of my invention result from the double looped cord employed in tying the mantle to the ring, the holding action of one loop preventing the draw of the mantle by the other loop so that all portions of the mantle in engagement with the ring will be und r about the same tension, the loops being hidden within the mantle fold. They further result from the use of a single knot which is made possible by the two loops, this knot being hidden in the mantle fold.

This application is a division of my ap plication Serial No. 609,194, filed February 17, 1911.

I claim:

1. An inverted incandescent mantle structure, comprising a mantle body and a supporting ring, said body having a circumferential fold at the ring secured by a plurality of cord loops having a knot, said loops and knot being hidden in the fold of the mantle body between the two plies thereof; substantially as described.

2. An inverted incandescent mantle structure, comprising a mantle body and a sup porting ring, having a circumferential fold around the ring secured by a single knot, the cord and knot being hidden in the fold between the two plies of the mantle body; substantially as described.

3. An inverted incandescent mantle struc ture, comprising a mantle body and a supporting ring, the mantle body having a circumferential fold at the ring secured by a plurality of cord loops having a single knot, the loops and knot being hidden within the fabric and lying between the two lies thereof around the ring; substantia ly as described.

4. The method of tying an incandescent mantle structure, consisting in assembling a mantle body open at both ends and a supporting ring within one end of the body, throwing a plurality of cord loops around the body and ring; knotting the same, and

- then turning the mantle inside out and closmy hand.
